To test Ho: 6 - 20 versus H1 : o

To test HOL 6-20 Versus HI : o < 20, a random sample of size n = 28 is obtained from a population that is known to be normally distributed.) (a) the samp e standard deviation is determined to be s = 13.8, compute the test statistic. (b) Ifthe researciner decides to test this hypothesis at the 0.05 level of significance, use technology to determine the Prvalue, (c) 'Will the !esearcher reject the null hypothesisQ Formula sheet The test statistic is 10 = O (Round to three decimal places as needed.) (b) The P-value is (Round to three decimal places as needed.) Y than the level of significance, the researcher (c) Since the P-value is G = 20. reject the null hypothesis
